i know my carbs were previously running rich (overfuelling) slightly, so im hoping i will be able to load a carb sync vaccum from someone so i can adjust accordingly. My understanding is that carb. balancing, (checking the vacuum), is done to ensure smooth running, particularly at idle speed. If the air/fuel mixture is suspect, exhaust waste gas analysis would be required to determine whether or not the carbs. are set up correctly. Modifications from standard, e.g. aftermarket air filters or exhaust systems will require the WG to be checked. Although if i suspected a slight fuel mixture problem i would get has analyse done, but when bike is idling you cab get an aroma of unburnt fuel and alsobwhen aomeone riding behind they say they can smell"taste" ones fuel Ao im doing a fuel carb check to the best i can, and if i cant resolve then it will be a garage job |

Interestingly, I have also followed a guy on a ZX636, his aftermarket can clearly shows signs of unburnt fuel, (black sooty deposits are visible), including as you say, the smell of petrol. Spark Plug colour/chop checks are a simple & effective way of determining whether the air/fuel ratio is correct.   |

 Well quick update on progress Oil and filter have been changed, sparks have been pchanged as main jet recomended it was difficult to get the plugs out for 1 and 4, possible but a pain. Radiator and pipes all plumed in with water in just to flush out then coolant to go in Carbsand air filter are bolted in and tank sat on. Tried to turn it over but battery needed more charge in it. So gunna to find where the opinate is as ive jist it in a safe place and not 100% if its been moved, Once it starts im draining the water and adding coolant checking double checking all the bolts and fasteners are tight. And then it sync the carbs and adjust if needed and make other adjustments if needed. |

Looking at the end can laid on the floor, it certainly isn't standard, what air filter are you running & is it clean. What year & model is the bike. Are the Carb. pilot mixture screws set correctly for idling. When on the throttle, the main jet size & needle height will determine the mixture. On some bikes, the needle height is adjustable, if not, a Dynojet Kit may be helpful. www.dynojet.co.uk/index.php/jet-kitsAt the end of the day, without WG Analysis, it's just guess work, or trial & error. |

Another update,
After a quick charge i tried starting the bike, it turn and turned and turn but no fire, so i temperarly put the exhaust to give it compression and the bike still didnt fire.
Upon a quick examination i hadnt connected a return pipe to the air box once that was connect the bike was trying to fire but nothing, left it a while as i suspect i may of flooded the engine while previosuly trying.
After about a 30 mins break i tried again and the bike fired and cut off and then fired.
So my todo list for the bike before its on the road again.
Exhaust installation with new gaskets.
Coolant to be added
Front sprocket to be installed from old engine.
Rear wheel to be re attached along witha chain tension adjustment.
Carb sync/pilot screws to be adjusted according to service manual.
Fairings to be installed.
Last but not least wash and police the bike ready for ita furst voyege

The can was on it when i got the bike but i dont think it is orginally, i have also cut it down due to damage on the exhaust so the jets wont be set correctly. Air filter is clean as clean can be, once again it was on the bike when i got it but dont think it a stock filter, looks like a K&N. |

Stage 1 kits are fully adjustable to allow the use of well- designed aftermarket pipes and K&N stock replacement air filters." |

Will look into this Dave once i have got the bike running and back on the road. hopefully it may not be needed urgently and i can get the man in the red suit of the way  anyway another quick update Gaskets turn up till yesterday (well turn up monday at work but i wasn't in till yesterday), so i was able to get my headers/manifold back on the bike, Filled my radiator and expansion tank with coolant. Replaced front sprocket with the one that matches the rear This just leaves start the bike up now and getting the coolant so has no air locks and to sync the carbs reinstall the rear wheel. Re install the rear wheel assembly. Adjust clutch and gear lever to the correct postions. most of this will get done tonight i hope and should be back on the road for the weekend. If it rains though it isn't becuase my bike is working again, its because stokesley fair is in town, Honest!!!! |

From left to right 4 3 2 1 Before After Im happy with results although not perfect, made the rookie nistake of connecting then back to front so when i intially come to sync them it was adjusting correctly. Today i figured out it was back to front reset the carbs sync and get it close as i gould get it. All is back on the bike and ready for a gentle run out |
